Hb500-Stahl
HB500 steel is a high-hardness wear-resistant material with a Brinell hardness around 500 HBW. It is engineered for extreme abrasion conditions where long service life and surface durability are critical.
Through its alloy composition and quenched-tempered microstructure, HB500 provides excellent resistance to wear in mining, Zement, Stahl, und Schüttguttransportindustrien.
While it offers superior wear performance, it should be selected carefully in applications where abrasion is dominant and impact conditions are within controlled limits.
- Beschreibung
HB500-Stahl is a high-hardness wear-resistant steel grade designed for severe abrasion and impact conditions. The “HB500” designation refers to its typical Brinell hardness level around 500 HBW, which indicates excellent resistance to surface wear. Es wird häufig im Bergbau eingesetzt, Zementproduktion, Steinbruch, Stahlwerke, and bulk material handling equipment.
HB500 steel is usually produced through quenching and tempering processes to achieve a hard surface combined with a controlled level of toughness.
Chemical Composition of HB500 Steel
HB500 is an alloyed carbon steel with controlled elements to achieve high hardness and wear resistance:
| Element | Funktion |
|---|---|
| Kohlenstoff (C) | Provides hardness and strength |
| Mangan (Mn) | Verbessert die Zähigkeit und Verschleißfestigkeit |
| Chrom (Cr) | Verbessert die Abrieb- und Korrosionsbeständigkeit |
| Molybdän (Mo) | Stabilizes hardness under load |
| Nickel (In) | Verbessert die Schlagzähigkeit |
The combination of these elements ensures a balance between hardness and structural reliability.
Main Mechanical Properties of HB500 Steel
| Eigentum | Leistung |
